What does Near and Far-infrared light mean?

Light within a visible, or non-visible, range.

Near-IR light is 940 nm, which is invisible to human eyes. It’s best used when indoors, like as a baby cam, as children will not see the red LED dots.

Far-IR light is 850nm, which is partially visible to human eyes. Far-IR is recommended for outdoor use, as they help the camera illuminate larger areas.
